Ibba, Francesco published the artcilePhotoinduced Multicomponent Synthesis of α-Silyloxy Acrylamides, an Unexplored Class of Silyl Enol Ethers, Synthetic Route of 17877-23-5, the publication is Organic Letters (2018), 20(4), 1098-1101, database is CAplus and MEDLINE.

The photoinduced, multicomponent reaction of α-diazoketones, silanols, and isocyanides affords α-silyloxy acrylamides, formally derived from α-keto amides. The presence of a secondary amido group makes classic preparative methods for silyl enol ethers unfeasible in this case, while the mild conditions required by this photochem. approach allow their synthesis in good yields; moreover, the general structure can be easily modified by varying each component of the multicomponent reaction. Fine-tuning of the reaction conditions (i.e., solvents, radiation, additives) can be exploited to obtain complete Z selectivity. The reactivity of this overlooked class of silyl enol ethers has been investigated, and features that could pave the way to new applications have been found.

Schuepbach, Bjoern published the artcileGrafting Organic n-Semiconductors to Surfaces: (Perfluoro-p-terphenyl-4-yl)alkanethiols, HPLC of Formula: 17877-23-5, the publication is European Journal of Organic Chemistry (2010), 3041-3048, database is CAplus.

Perfluoroterphenyl, an organic n-semiconductor, has been derivatized by short ω-mercaptoalkyl chains to permit the formation of self-assembled monolayers on semiconductor and coinage metal substrates. Because the perfluoroaryl rings are prone to nucleophilic attack, strategies for the introduction of the side chains had to be developed that avoid the use of any nucleophiles. Keeping this in mind, the resp. derivatives with one, two, and three methylene groups in the alkyl linker could be obtained in good yields. The crystal structure of one of the intermediates, (perfluoroterphenyl-4-yl)methanol, exhibits a parallel arrangement of the mols. as well as a helical structure of the perfluoroterphenyl part, which is in contrast to the structure found for most nonfluorinated terphenyl derivatives Using Au(111) as a test substrate, it could be demonstrated that all three thiols form dense monolayers with a pronounced odd-even effect governed by the parity of the number of methylene groups in the alkyl chain.

Marciniec, Bogdan published the artcileSynthesis, first structures, and catalytic activity of the monomeric rhodium(I)-siloxide phosphine complexes, Product Details of C9H22OSi, the publication is Canadian Journal of Chemistry (2003), 81(11), 1292-1298, database is CAplus.

Four new square-plane rhodium siloxide complexes of the general formula [Rh(cod)(PR₃‘)(OSiR₃)] (R = Me, i-Pr, O-t-Bu, R’ = Cy, Ph) were synthesized and the structures of three of them were resolved by the x-ray method. [Rh(cod)(PCy₃)(OSiMe₃)] (1) appeared to be a very efficient catalyst for hydrosilylation of allyl glycidyl ether to yield, selectively, 3-glycidoxypropyltriethoxysilane, a com. important silane coupling agent. Catalytic measurements and stoichiometric experiments of 1 with triethoxysilane suggest a mechanism where an unsaturated Rh-H species is responsible for the catalysis.

Lin, Jian-Dong published the artcileWettability-Driven Palladium Catalysis for Enhanced Dehydrogenative Coupling of Organosilanes, Name: Triisopropylsilanol, the publication is ACS Catalysis (2017), 7(3), 1720-1727, database is CAplus.

Direct coupling of Si-H bonds has emerged as a promising strategy for designing chem. and biol. useful organosilicon compounds Heterogeneous catalytic systems sufficiently active, selective, and durable for dehydrosilylation reactions under mild conditions have been lacking to date. Herein, we report that the hydrophobic characteristics of the underlying supports can be advantageously utilized to enhance the efficiency of palladium nanoparticles (Pd NPs) for the dehydrogenative coupling of organosilanes. As a result of this prominent surface wettability control, the modulated catalyst showed a significantly higher level of efficiency and durability characteristics toward the dehydrogenative condensation of organosilanes with water, alcs., or amines in comparison to existing catalysts. In a broader context, this work illustrates a powerful approach to maximize the performance of supported metals through surface wettability modulation under catalytically relevant conditions.

Gitis, Vitaly published the artcileOrganosilane oxidation by water catalysed by large gold nanoparticles in a membrane reactor, Recommanded Product: Triisopropylsilanol, the publication is Catalysis Science & Technology (2014), 4(7), 2156-2160, database is CAplus.

We show that gold nanoparticles catalyze the oxidation of organosilanes using water as oxidant at ambient conditions. Remarkably, monodispersions of small gold particles (3.5 nm diameter) and large ones (6-18 nm diameter) give equally good conversion rates. This is important because separating large nanoparticles is much easier, and can be done using ultrafiltration instead of nanofiltration. We introduce a simple setup, constructed inhouse, where the reaction products are extracted through a ceramic membrane under pressure, leaving the gold nanoparticles intact in the vessel. The nominal substrate/catalyst ratios are ca. 1800 : 1, with typical TONs of 1500-1600, and TOFs around 800 h^-1. But the actual activity of the large nanoparticles is much higher, because most of their gold atoms are “inside”, and therefore unavailable. Control experiments confirm that no gold escapes to the membrane permeate. The role of surface oxygen as a possible co-catalyst is discussed. Considering the ease of product separation and the robustness of the ceramic membrane, this approach opens opportunities for actual applications of gold catalysts in water oxidation reactions.

Masaoka, Shin published the artcileThe synthesis of chlorosilanes from alkoxysilanes, silanols, and hydrosilanes with bulky substituents, Application of Triisopropylsilanol, the publication is Journal of Organometallic Chemistry (2006), 691(1-2), 174-181, database is CAplus.

We have found that com. important trialkylchlorosilanes can readily be synthesized by the reaction of alkoxysilanes, silanols, and hydrosilanes with aqueous concentrated hydrochloric acid. Treatment of trialkylalkoxysilanes bearing bulky alkyl substituents, such as the i-Pr, sec-Bu, tert-Bu, and cyclo-Hex group, with 35% aqueous hydrochloric acid afforded the corresponding trialkylchlorosilanes in excellent yields. Similar treatment of trialkylsilanols with 35% aqueous hydrochloric acid also gave trialkylchlorosilanes in almost quant. yields. The reaction of methyltrichlorosilane and dimethyldichlorosilane with alkyl Grignard reagents bearing a bulky alkyl group, followed by treatment of the resulting mixtures with aqueous concentrated hydrochloric acid, produced the resp. dialkylmethyl- and alkyldimethylchlorosilanes in high yields. Treatment of trialkylhydrosilanes with concentrated hydrochloric acid in the presence of a palladium catalyst afforded trialkylchlorosilanes in high yields.
